What it plays
Plays up to: PSP. Chip: RockChip RK3576S.
Scores out of 100. 100 means the system runs at full speed with no known issues on this device. 80 or more plays well (green), 50 to 79 plays partly (yellow).
What the specs mean
10:9 screen
Exactly the Game Boy's shape. Everything else shows bars.
Based on: Display math: native screen shapes of each system
Game Boy at exactly 10x
160 x 144 times 10 is the screen's own 1600 x 1440, so Game Boy pixels stay perfectly even with no filter and no bars.
Based on: Display math: native resolution x whole-number scale = screen resolution
2 GB of memory rules out Switch
The Switch has 4 GB of memory of its own. An emulator has to hold all of it and Android on top, which does not fit here.
Based on: Hardware fact: the Switch has 4 GB of RAM
Digital triggers
The GameCube's triggers were pressure sensitive, and a few games use a light press, such as spraying while you walk in Super Mario Sunshine. Here the triggers are on or off.
Based on: Hardware fact: GameCube controller triggers are analog; this device is not listed with analog triggers
Shoulder buttons in a row
L1 and L2 sit side by side along the top edge instead of stacked. PS2 games that need L1 and L2 together mean sliding one finger between them.
Based on: Layout data (shoulder button layout)
One analog stick
PS2 and GameCube games often put the camera on a second stick. With one stick, the camera moves to buttons.
Based on: Layout data; PS2 and GameCube controllers have two sticks
DS on one screen
DS games show both screens shrunk side by side, or one big screen you swap. The touch screen stands in for the stylus.
Based on: Layout data: single screen with touch
Android 14
Besides emulators it runs Android games and game streaming apps, from your PC or the cloud.
Based on: Operating system data
